Much like other new weapons seen during the Great War, the first anti-aircraft guns were crude in nature. Some of the first British AA weapons would be 13-pound guns mounted in the bed of a Thornycraft J-type lorry. This equipment would also be accompanied by two other lorries carrying range-finding equipment and ammunition.

Early AA weapons faced new problems never seen before in combat. Unlike ground targets, aircraft can effectively move in three dimensions. The weapon would not only have to accurately target the aircraft, but also fire rounds with enough velocity to reach great altitudes. These techniques would be refined as the war continued, but little data exists as to how effective these weapons were in downing enemy aircraft.
